  15. Turn ignition off. Disconnect RCDLR electrical connector. See COMPONENT LOCATIONS  . Using a test light connected to ground, backprobe RCDLR 4-pin connector terminal No. 1 (Orange wire). See Figure . If test light illuminates, go to next step. If test light does not illuminate, go to step  25 .
  16. Connect test light between RCDLR 4-pin connector terminals No. 1 (Orange wire) and No. 4 (Black/White wire). If test light illuminates, go to next step. If test light does not illuminate, go to step  24 .
  17. Connect Red lead of DVOM to RCDLR 4-pin connector terminal No. 2 (Orange wire). Connect Black lead of DVOM to ground. Turn ignition on, engine off. DVOM should display battery voltage. If battery voltage exists, disconnect DVOM and go to next step. If battery voltage does not exist, go to step  20 .
  18. Ensure ignition is on, engine off. Using a test light connected to ground, backprobe RCDLR 4-pin connector terminal No. 2 (Orange wire). If test light illuminates, go to next step. If test light does not illuminate, go to step  21 .

If open circuit, high resistance or short to ground is found in Orange wire, repair as necessary and go to step  27 . If open, high resistance or short to power is not found in Orange wire, go to step  22 .
  21. Check for poor connection at RCDLR 4-pin connector. If poor connection is found, repair as necessary and go to step  27 . If connection at RCDLR 4-pin connector is okay, go to step  25 .
  22. Check for poor connection at BCM. If poor BCM connection is found, repair as necessary and go to step  27 . If BCM connection is okay, go to step  26 .
  23. Repair open, high resistance or short to ground in battery positive voltage circuit (Orange wire) of RCDLR. After making necessary repairs, go to step  27 .
  24. Repair open or high resistance in RCDLR ground circuit (Black/White wire). After making necessary repairs, go to step  27 .
  25. Replace RCDLR. See REMOTE CONTROL DOOR LOCK RECEIVER  under REMOVAL & INSTALLATION.
